Well, you did do a hit of kif (THC crystals), doing hot knives. It's a good enough headfuck just using a small waterbong smoking kif, but man, you did a hit the quickest and best way to smoke, with the most potent part of the flower. Of course you'll black out!!! I get dizzy when I do a knife hit of just ganja or hash. Oil is the best and I have seen a girl go into a small seizure where her eyes rolled back in her head, after an oil hit.

Kif is much more potent though. Next time, smoke kif with a bong. That will fuck you up enough. You just over did it.
